Parasitic draw kills battery

[BennyLava]

Hi all. I am having an issue with my wife's 2003 nissan altima. Its the 2.5L 4cyl. The battery dies overnight and the car won't start in the morning. I took the battery to 3 different stores, and all 3 said its a good battery. I even made one use their big machine, which I assume actually load tests the battery. I have tried several of the nissan forums, but it is difficult to get anyone to reply, or the forums are dead. Not sure which. So since its a basic problem, and not really manufacturer specific, I figured I'd post it here. Over the years I've noticed we got some real smart people here so its worth a shot.

At this point, I guess the problem I'm having, is either I'm confused, or my multimeter is. So I hooked the multimeter up to the negative battery terminal, in order to see how many amps were being wasted.

As you can see in pic 1, I have a parasitic amp draw of .252 amps. Also known as, 252 milliamps. But if you look at the second pic, I changed the setting to milliamps. Now somehow its saying that I've only got a parasitic draw of 2.52 milliamps. It would seem that the meter is confused about where to place the decimal point. Typically you're not supposed to have a parasitic draw over 50 milliamps. So clearly 252 milliamps, is about 200 too many. So that could be killing the battery overnight.

But on the other setting, the milliamps setting, the meter is saying that its WAY below 50 milliamps, and the draw is in fact only 2.52 milliamps. So which is it? Am I doing it wrong?
